[GREENFOOT-185] getObjects method requires casting

At the moment, the getObjects method in the World class seems to return a list of type Objects no matter what the class specified in the parameter is. Would it not make more sense to use generics to return a list of the class specified in the parameter, or return a list of type actor if null is specified?
